Flutter问题小记

Q1: 执行flutter packages get时一直提示Running "flutter packages get" in project_name...

A1: 很大可能就是packages获取地址被墙了。具体操作

  • Linux 或 Mac

修改当前用户的~/.bash_profile vim 打开这个文件，添加

export PUB_HOSTED_URL=https://pub.flutter-io.cn
export FLUTTER_STORAGE_BASE_URL=https://storage.flutter-io.cn

source ~/.bash_profile让配置生效。

  • Windows

新增两个环境变量

PUB_HOSTED_URL ===== https://pub.flutter-io.cn
FLUTTER_STORAGE_BASE_URL ===== https://storage.flutter-io.cn

Q2: 执行flutter packages get时一直提示Waiting for another flutter command to release the startup lock

A2: 解决方法

  1. 打开flutter的安装目录/bin/cache/
  2. 删除lockfile文件
  3. 重启AndroidStudio

Q3: 正确的添加添加Flutter sdk 路径

A3: 解决方法

打开(或创建) $HOME/.bash_profile. 文件路径和文件名可能在您的机器上有所不同.

添加以下行并更改[PATH_TO_FLUTTER_GIT_DIRECTORY]/flutter为解压后Flutter的路径:

export PATH=PATH_TO_FLUTTER_GIT_DIRECTORY/flutter/bin:$PATH

运行 source $HOME/.bash_profile 刷新当前终端窗口.

Q4: AndroidStudio 运行报错

Error connecting to the service protocol: HttpException: , uri = http://127.0.0.1:8113/ws

A4: 解决方法 打开 XCODE - Window - Devices and Simulators，找到用来调试的设备取消勾选 Connect via network。
